IMPROVEMENT IN CAR-COUPLINGS.

Specification forming part of Letters Patent No. 141,278, dated July 29, 1873; application filed February 1, 1873.

To all whom it may concern:

Be in known that I, GEBHARD KOEB, of Springfield, in the county of Clark and State of Ohio, have invented a new and useful Improvement in Oar-Coupling, of which the fol lowing is a specification Figure l is a top View of my improved carcoupling. Fig. 2 is a detail vertical section of the same taken through the line m0, Fig. 1.

Similar letters of reference indicate correspondin g parts.

The invention consists in the improvement of car-couplin gs, as hereinafter fully described and pointed out in the claim.

A is the bumper or body of the car-coupling, which is connected with the body of the car by the draw-bar B. The mouth of the bumper is made hopper-shaped, and with a horizontal opening or slot between the inner edges of the upper and lowerinclined sides of said mouth, as shown in Fig. 2. O is a wedge-shaped or triangular cavity, the upper and lower inclined sides of which meet the upper and lower inclined sides of the mouth of the bumper-head, just in front of the hole for the couplingpin, so as to form angles or ribs a which angles or ribs a serve as fulcrums to the couplinglink D, to allow its outer end to be raised to enter the bumper-head of the adjacent car by lowering its inner end. E is the coupling-pin, which passes down through a hole in the up.- per and lower parts of the bumper, as shown in Fig. 2. Upon the rear side of the pin E is formed, or to it is securely attached, rack-teeth F, into the teeth of which mesh the teeth of ,own weight.

the small gear wheel G, attached to the rod H by screws, keys, or other convenient means. The rod H passes through and works in holes in the flanges 0?, formed upon the upper side of the bumper A, and which rise sufficiently high to protect the gear-wheel G. The ends of the rod H extend out to the side of the car and terminate in cranks, hand-wheels, or other convenient means for operating the said rod. The lower end of the rack F forms a shoulder, which rests upon the inner end of the link I), so that by turning the rod H and gear-wheel G in the direction to force the pin E downward, the inner end of the link I) will be forced downward, raising the outer end of the said link to adjust it to enter the bumper-head of the adjacent carp As the pin E is raised, the outer end of the link I) will drop by its spring, I, havinga ball or knob upon its outer or free end, to enter depressions or strike against ribs formed in or upon the side of the flange c to hold the pin E in any position into which it may be adjusted.

' Having thus described my invention,I claim as new and desire to secure by Letters Patent- The bumper A having ribs 0. and cavity 0, combined with pin E having rack F and the coupling-link. D, as and for the purpose de- GEBHARD KOEB.
